Thinking about adding a Brush Guard

[PastaPower]

Does anyone have any opinions on Brush Guards? I have been thinking about adding a Brush Guard but would like to know if they are more of a PITA than they're worth. I'm not looking to go off-roading into the woods, I just like the way they look on a Hummer. Are they hard to clean underneath...do they have a tendency to scratch the body? Do I go with Chrome, S.S. or OEM Black? Single, Dual, or wrap around? I know this is a personal taste issue here but opinions are much appreciated. I see an aweful lot of them for sale on eBay (take offs)and was worried that maybe they are'nt worth the expense.
